Answer:
b. The number of electrons
Explanation:
A "neutral atom" has a <u>neutral charge</u>. This means that <em>its charge is equal to </em><em>zero. </em>In order for the charges to cancel out each other, the atom's <em>positive charge should be equal to the negative charge. </em>These being said, the number of electrons<em> (negatively-charged)</em> is then equal to the number of protons <em>(positively-charged). </em>Those atoms which are not neutral are called <em>"ions."</em> This means that they either have more or less electrons than the protons.
Answer:
the coefficients are equal
Explanation:
Answer:
90g
Explanation:
The equation for the reaction is given below:
2H2 + O2 → 2H2O
From the equation above,
1 mole of O2 produced 2 moles of H2O.
Therefore, 2.5 moles of O2 will produce = 2.5 x 2 = 5 moles of H2O.
Now let us convert 5 moles to H2O to grams to obtain the desired result. This is shown below:
Molar Mass of H2O = (2x1) + 16 = 2 + 16 = 18g/mol
Number of mole of H2O = 5 moles
Mass of H2O = ?
Mass = number of mole x molar Mass
Mass of H2O = 5 x 18 = 90g
Therefore, 90g of H2O are produced
